Pale Blue Flowers Bring a Softer Glow to the Shade Garden Opal Lungwort brings luminous spring color into shaded garden beds with clusters of pale blue flowers that can appear almost white in cool light. The blossoms begin as soft pink buds before opening to a clear opal-blue, allowing pink and blue tones to appear together on the plant. Its light flower color makes Opal especially useful in areas where deeper blues, purples or reds might disappear into the shade. The blooms catch available light beneath trees and shrubs, creating a brighter effect along woodland paths, shaded foundations and partially enclosed garden spaces. Opal is also a freely flowering cultivar. A mature plant can carry a generous display of funnel-shaped flowers during its spring bloom period, giving this compact perennial more impact than its modest height might suggest. The cool blue coloring pairs easily with white hellebores, yellow woodland flowers, burgundy heucheras, and fresh green fern fronds. It is equally attractive in quiet monochromatic gardens or more colorful cottage-style combinations. Shell-Pink Buds Open into Opalescent Blue Spring Blooms The flower show begins with pale pink buds held in branched clusters above the foliage. As the buds open, the flowers shift through pale lavender and blue tones, eventually fading toward an icy blue-white. This color change is one of the most appealing features of Opal Lungwort. Several stages can appear at once, giving the plant a softly multicolored look without the stronger contrast found in darker lungwort cultivars. Opal typically blooms from March through May, depending on the growing zone and seasonal temperatures. Its early flowering period helps fill the gap between late-winter bulbs and the main flush of spring perennials. The blossoms provide nectar and pollen for bees and other beneficial insects emerging early in the season. Although the flowers are visually delicate, they are carried on stiff stems that rise clearly above the foliage. Silver-Spotted Leaves Extend the Display Beyond Spring Opal Lungwort remains attractive after its flowers have faded. Its broad green leaves are densely marked with silver spots and splashes, producing a bright foliage mound that continues to add texture throughout the growing season. The silver pattern is heavier than that of many older common lungwort selections. This makes Opal useful as a foliage plant as well as a flowering perennial, especially beneath shrubs and trees where solid green leaves can blend into the background. Mature leaves are oval to elongated, roughly textured, and softly hairy. They form a low, dense clump that spreads gradually through short, creeping roots without behaving like an aggressive running groundcover. The foliage may remain semi-evergreen in regions with mild winters. In colder climates, leaves decline after hard freezes commonly and are replaced by fresh growth in spring. A Compact Groundcover for Paths, Borders, and Woodland Beds Opal Lungwort generally grows 10 to 14 inches tall and spreads approximately 12 to 18 inches wide. Its low, bushy habit is substantial enough to cover open soil without obscuring taller shade perennials planted behind it. Use Opal along shaded walkways, at the front of woodland borders or beneath high-branched shrubs. Several plants can be repeated to create a silver-spotted groundcover, while a single plant can brighten a small opening among hostas, ferns or hellebores. Its spreading clumps are also useful for softening the base of deciduous shrubs and filling spaces between spring-flowering bulbs. Because the foliage develops as bulb leaves begin to decline, Opal can help hide the fading growth of daffodils and other early bulbs. Opal can grow in a shaded container when supplied with consistent moisture and good drainage. Choose a broad pot that allows the clump to widen, and protect container-grown roots from extreme winter temperatures. Cool, Moist Soil Keeps Opal Lungwort Looking Its Best Plant Opal Lungwort in partial shade or full shade. Bright filtered light or gentle morning sun can support good flowering, but strong afternoon sun may scorch the foliage, particularly in hot climates. The ideal soil is rich in organic matter, consistently moist, and well-drained. Compost and leaf mold help create the cool woodland conditions lungwort prefers. Avoid both standing water and locations that become severely dry during summer. Opal may tolerate clay, loam, or chalky soil as long as drainage and moisture remain balanced. It also adapts to acidic, neutral, and mildly alkaline soils, making it less demanding about pH than many shade perennials. Remove faded flower stalks and tired, older leaves after blooming to encourage a fresh flush of foliage. Powdery mildew can develop when plants become dry or crowded, so provide steady moisture and enough spacing for air to circulate. Deer and rabbits generally avoid the textured foliage, although no plant is entirely browse-proof.
